The Sarto Raso deserves components every bit as considered as the frame itself. The Darimo Carbon Seatpost for Sarto Raso gives you a dedicated, ultra-light upgrade designed specifically for this exceptional Italian road bike.
Choose between Straight and +15mm Setback versions, then select the correct seatpost length for your frame size, saddle height and required insertion.
Built for the Sarto Raso
Darimo has developed this seatpost specifically for the Raso, giving Sarto owners the opportunity to reduce weight without moving away from the frame-specific seatpost design.

- Ultra-light carbon construction
- Straight or +15mm setback
- 250, 300, 350 and 400mm lengths
- Made by Darimo in Spain
Straight or +15mm setback?
The difference is about achieving your correct saddle position.
Straight is the option for riders requiring the more forward saddle position.
+15mm Setback moves the saddle position rearward, providing additional setback for riders whose fit requires it.
If you're happy with your existing position, the goal is to reproduce that position with the Darimo rather than choosing an offset simply because one sounds preferable.
Choose the correct seatpost length
Darimo offers the Raso seatpost in 250, 300, 350 and 400mm lengths. The correct choice depends on your saddle height and how much of the post will sit inside the frame.
Use the sizing table below to check the required length before ordering. The aim is to choose the appropriate length for your position rather than automatically selecting the longest post available.
FAQs
Is this seatpost made specifically for the Sarto Raso?
Yes. This is Darimo's dedicated carbon seatpost for the Sarto Raso rather than a universal round seatpost.
Should I choose Straight or +15mm Setback?
Choose the version that gives you the saddle position required by your bike fit. If your current position is correct, use that as the reference when selecting the Darimo version.
Which seatpost length should I choose?
Darimo offers 250, 300, 350 and 400mm lengths. Use the sizing table above to determine the shortest suitable post that provides the required saddle height and correct insertion for your Raso.
If you're unsure, contact us with your current setup before ordering and we can help confirm the appropriate length.
Can I simply order the 400mm post and cut it down?
No. Darimo seatposts are engineered around their specified length and should not be cut. Choose the correct length when ordering.
What if I'm unsure about the offset or length?
Contact Bspoke Velo before ordering. We can help you work through the required Raso version and seatpost length before the order is placed.
